--------------------------------------
[~zzztimbo] Could you provide the full stack trace so that I can confirm if
this is because of the negative cache. If the root cause is a
FileNotFoundException and the file name is a random UUID, I'm pretty sure
that's due to the negative cache. If not, then probably because of other issues.
